单片机是一种集成电路芯片，是采用超大规模集成电路技术把具有数据处理能力的中央处理器（CPU），随机存储器（ＲＡＭ），只读存储器（ＲＯＭ），多种Ｉ／Ｏ口和中断系统、定时器／计数器等功能（可能还包含显示驱动电路、脉宽调制电路、模拟多路转换器、Ａ／Ｄ转换器等）集成到一块硅片上构成的一个小而完善的微型计算机系统。(Singlechip is an integrated circuit chip. It is a central processor (CPU), random memory (RAM), read-only memory (ROM), a variety of I / O ports and interrupt systems, timer / counter and so on. The circuit, the pulse width modulation circuit, the analog multiplexer, the A / D converter, etc. are integrated into a small and perfect microcomputer system made up of a piece of silicon chip.)

采用STC12C5A60S2单片机发生47KHZ的PWM脉冲信号，经过IR2104控制MOS，从而控制整个BUCK电路。单片机内部自带的10位ADC能通过电压电流检测电流实时反馈电流和电压数值，并由此调整输出的PWM的占空比，形成电流电压闭环控制系统。按键能设置输出电流从0.2A到2A，以0.01A递增，输出最大10V，液晶能显示实时输出电流与电压(use STC controller to generate pwm signal ，whic can dribe mos pipe，then control buck circuit)

GSM模块AT命令组装和AT命令响应解析程序。实现了自动组装标准AT命令并发送到GSM模块，同时可以提取GSM模块输出的所有AT命令，同时实现了大量AT命令响应的解析工作。主要的过程采用了Contiki的进程模型。(Making and parsing routine for AT commands of GSM module. It can automatically make standard AT commands and sent it to GSM module, while it can get all the AT commands sending GSM module, and analysis a large number of AT command responses. The main process uses a process model of Contiki.)

说明：  计算机编程手册（CPM）提供程序员理解如何编程给定计算机所需的信息。 本手册主要关注计算机本身，而不是计算机上运行的特定软件。(The Computer Programming Manual (CPM) provides information needed by a programmer to understand how to program a given computer. This manual focuses on the computer itself, not on particular software that will run on the computer.)
